The issue was significantly over-subscribed, with orders for EUR 11 billion collected, the Finance Ministry said Tuesday evening.

The high demand "confirms investor trust in Slovenia's credit rating and the firmness of the Slovenian economy and fiscal policy," the ministry said.

The bond issue makes Slovenia the first eurozone country to tap the bond market this year and the issue size covers almost the entire planned borrowing of EUR 1.58 billion for 2020.

It comes at a time when investors are looking for safe investments amidst continued global uncertainty, which has been driving down bond yields across the eurozone.

The yield on Slovenia's 10-year benchmarks was just above zero yesterday, according to data on the MTS Bonds.com platform.

The bulk of the latest issue was purchased by fund managers (52%), followed by pension funds and insurers (18%), and banks (14%).
